PUMP-PLUNGER.

SPECIFICATION forming part of Letters Patent N o. 474,365, dated May 10, 1892.

Application filed October 2l, 1891. Serial No. 409,415. (No model.) l

To @ZZ wwm, it may concern.'

Be it known that I, WILLIAM P. CARLIN, a citizen of the United States, residing at Jeffersontown, in the county of Jefferson and 5 State of Kentuclzy, have invented a new and useful Pump-Plunger, of which the following is a specification.

This invention relates to improvements in that class of pumps in which a stationary ro plunger andmovable cylinder are employed; and the objects in view are to provide a plunger of cheap and simple construction, possessing great durability, the parts of which are accessible, easily renewed, and to avoid the employment of a valve in the bottom of the cylinder, whereby the entrance of sand and grit is obviated,and,iinally, to provide a cheap and simple means for supporting the side valves of the plunger therein.

2o Other objects and advantages of the in vention will appear in the following` description, and the novel features thereof will be particularly pointed out in the claim.

Referring to the drawings, Figure l is a vertical longitudinal section of a pump constructed in accordance with my invention. Fig. 2 is an enlarged vertical section of the plunger. Fig. 3 is a detail in perspective of the metal clamp employed for securing the 3o side valves of the plunger in position.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 designates the cylinder, which is closed at its bottom and above the same provided with a series of perforations designed to act as a strainer for the water to be pumped. Ordinary mechanism (not shown) is employed for vertically reciprocating the cylinder,

which cylinder is immersedin the well 2. EX-

4o tending downwardly into the cylinder is the stationary discharge-pipe 3, and the same has screwed to its lower end the cylindrical valvechamber et of the plunger. The valve-chamber is provided with the usual interval-perforated guide-bar 4', in which operates the stem of the clack-valv'e 5. The lower end of the chamber is threaded interiorly and rcceives the upper reduced end of a valve-seat '7, formed upon the upper end of the plunger- 5o chamber 8. T his plunger-chamber 8 is provided with external vertical ribs 9 and between the same with transverse slots or inletports 10. These slots are covered by leather or other flexible valves 1l, each of which is connected removably to the interior of the plunger-chamber by means of an inverted L-shaped metal clamping-plate 13, through which screws 14 are passed. The screws 14 have their heads countersunk in the vertical ribs of the plunger and their bodies passed 6o through said ribs, the wall of the plunger, the leather valves, and clamping-plates.

15 designates a clamping-ring having an upper reduced threaded end 16, which screws into the lower end of the plunger-chamber. The ring is encircled by a leather packingring 17, the inner edge of which is clamped by the clamping-ring against the lower end of the plunger.

In operation the cylinder is reciprocated 7o vertically, the water entering into the perforations above the cylinderand being thereby strained. As the cylinder descends the water it contains is forced through the side valves or inlet-ports into the plunger, which valves yield to the inward pressure of water and permit its passage. Upon the return or upstroke of the cylinder the inlet-ports are closed by their flexible valves, while the body of water forces its way up through the plun 8o ger, raising the check-valve from its seat, and

,passes on up through the discharge-pipe.

The advantages over the ordinary pu mp will be obvious from the foregoing description,and might be enumerated briey as follows: The valves are more durable, more easily replaced, valves and bottom cylinder are omitted, which are soon beaten ont when present, the closing of the lower end of the cylinder and the perforating of the same prevents the admission 9o of sand and grit, the discharge-passage of the pump is not occupied by any plunger-rods, dac.

Having described my in vent-ion, what I claim is- In a pump of the class described, the com- 9; bination, with the cylinder closed at its ends and. provided with perforations, of a discharge-pi pe, a valve-bod y secured to the lower end of the same, a valve therein, a plunger having reduced upper ends forming the valverco seat, threaded in the valve-chamber and having an internally-threaded lower end, said plunger having vertical external ribs and between the same provided with transverse slots forming inlets, L-shaped clamping-plates located upon theinner side of the plunger opposite each of the ribs, screws countersunk in the ribs passing through the same, the wall of the plunger, and the clamping plates, leather valves interposed between the plates and wall of the plunger, a clamping-ring threaded in the lower end ofthe plunger, and a leather packing-ring interposed between the lower end of the plunger and clampingring and secured in position by the latter, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
